"He’s hungry," Griffin said during a conference call with Baltimore reporters. "I’ve told people time and time again, there are a lot of great football players out there, and a lot of them don’t get drafted. So when you have a sixth-round guy, don’t just automatically assume that he’s not going to be verygood.

"So, he worked his way through the offseason, worked extremely hard, learned the whole offense, and he just runs harder than anybody in the league right now.”

Morris' attitude sets him apart as well.

"The guy runs angry," Ravens defensive coordinator Dean Pees said. "That’s the way I explained it to our guys. That’s a good thing for them. He runs hard, he runs behind his pads. He’s been a force.

"I think the scheme has helped him, not only the zone scheme, but the dive scheme off the option and stuff. The guy has really been a good back, and he runs hard.”
